A method for the nucleophilic trifluoromethylation of salicyl aldimines, which do not contain an activating group at the nitrogen atom, has been described. The reaction proceeds through the initial generation of intramolecular boron complex followed by interaction with Me3SiCF3 activated by sodium acetate.

Nucleophilic addition of the pentafluorophenyl group from (C6F5)3SiF to non-activated imines affording α-C6F5-substituted secondary amines in high yield has been described. The reaction proceeds via simultaneous activation of imines and the silane reagent by means of a proton and chlorideion, respectively.
已经描述了将来自(C 6 F 5)3 SiF的五氟苯基亲核加成到未活化的亚胺上,从而以高收率提供α- C6 F 5取代的仲胺。通过分别借助于质子和氯离子同时活化亚胺和硅烷试剂来进行反应。
